ll designates a gas burner lower portion of the body part of the stove and positioned beneath the oven '2 so that llic latter may he heated satisfactorily in case the gas burner is used instead of a coal or other l'uel burning fire box. The gas hurner ll receives its gas from the conduit 1;! which is connected to the gas supply pipe 1 and is controlled hy any well known type ol' valve l-l. The supply pipe 13. in thc present instance. extends vertically at onc side ol the range structure and is pro-- vidcd with a pair o'l branches l5 and ll) controlled respeclively hy hand valves lland llw. as will he readily raider-stood. The hranch 1-). in the present instance, extends within the hood ill which is positioncd as customary ahove the top 5 ol the range where the said hranca teriuinahss in a huruer ill locatcd licneath the inking): coniparlnicnt 21. The. branch ill also extends within the hood and terminatcs in a hurucr '22 located in the top part ol the hroilcr compartment :23. as will hc understood.

2% dcsignates the line which communicates at its lower end with the combustion chain her of the body part l of the range and passes upwardly at the rcar of the hood hack of the broiler compartment 23. This flue conducts the products ol conihustion to a suitable chii'nncy or vent. not shown.

In the prcscnt instance. l have utilized the usual waste space at the rear ol the water tank or boiler 25 and also extending: in rear of the, broiler cou'ipartuient -2 hy prov'idingf a plate or partition Ell) 'E'Ol'illllhil' vilih the walls of the hood a l'ieat-ing chau1- her 27 containing the \atcr heating coil 28 which is heated by means of the gas burner 29. This burner is supplied with from a branch pipe, 30 leading from the pipe 15 and controlled hy a suitahle valve so that it may he operated independontly of the hurncrs 20 and 22. The hottom 30 of the, chanihor 27 is closed so as to prevent the falling of particles from the chamber 27 on to the top of the stove underneath the hood. It will he understood that as usual the space upon the top of the stove and underneath the hood free in order that vesscls containing: cooking or cooked food may he pushed to the rear of. the top of the stove. If thc bottom of the charnher 27 wore provided with an opening or openings it might happen that particles of foreign matter would drop down therethrough into the Food contained in vessels. The air for supplying oxygen for combustion to the hurner 29 is supplied through an opening 30 in the rear wall of located in the Y such. water from the said coil the chanihcr. 'lhc gases from the. chanihcr are permitted to escape through the open lng'l-l through the top of the clnunhcr.

J1 and 32 designate rcspectivcly circulating pipes for conveying water from the wator hack l to the hoiler or tank 25 in the customary manner. the heated water ascend ing in thc pipe 31 while tho water of lower temperature descends in thc pipe to the bottom of the water hack -l.

In other words. the water in thc coil 3% is allowci to remain cool. in such case. unless uurans wcrc provided to prevent such llLLlll'l'UllUt. it might happcn that hot water would escape from thc tank through the pipe leading ll'Ulll lhe lop part l'hcrco'l shown in hip. J and pass into thc rcccptaclc ll To prevent such occurrence l have provided l'lll valvc h? in the pipe Ill) leading. lroin the rcccplacle ill. The receptacle ll! is silualcd ilunicdiidely ahovc the top of llic heating chauihcr 2'? and in tho paih ol' the hot conihustion products which are discharged through the opening ll. This receptacle is adaptcd l'o hold a relatively small hody of water which may he h *ale l quickly for the purpose. ol supplyinghpt water quickly as when a llo11:--1cshould he tho case. she would ignite the hurncr 2:) and thc heat therefrom would quickly heat thev water in the coil 25% and in the receptacle 40. the two together holdion the. requirml quantity of water. it will thus he seen that when a relatively small quantity of water is desired it may hc quickly furnished by the means justdescribed. At such time ii the valve 42 is closed no water can pass to the delivery pipc 37 from the tank 25 hut is 'l'rco to pass to such pipc 'll'Olll the receptacle -l() and tho coiled pipe .28 provided the valve opcn as it must he when it is desired to draw 28 and receptacle. 40.

The receptacle 40 is provided with a diaphragm cover 4? serving; a purpose which ll ll" lll mamas may be described in. connection with the operation of the gas burner to which I have previously referred. The burner 29 for heating the coil 28 in the chamber 2'! preferably is automatically controlled by theexpansion and contraction of the coil :28 and its adjuncts. including an outward movement or a movement of expansion of the diaphragm i3.

For the purpose of controlling the supply of gast'o the burner I have. provided a cutoil valve ll'which is adapted for sliding movement across the discharge outlet of the Bunsen burner which valve is carried by a' lever 46 fulcrumed at l7 to a suitable bracket 48 or the like which is supported upon any suitable part of-the range 'structure.

X49 designates a rod connected at one end to the lever 46 near the pivot of the 1: tier. said rod having at its opposite end a lab orally disposed arm 50 which has threaded engagement with a stud bolt 51 the 0 antingend of which bears against a sin able abutment 52 which is situated upon the central part of the diaphragmld In case of excessive pressure due to the overheating of the water within the receptacle ill the diaphragm 43 is forced outwardly thereby actuating the arm 50 to shift the rod 49 longitudinally and consequently impart pivotal movement to the lever 46' to cause a slidingmovement of the valve 44 across the outlet if) of the burner to thereby cut down the supply of gas in the desired manner. As an adjunct to this automatic control I have also canploveda second arm 53 which is' suitabl v secured to the rod 49 intermediate its ends and .projectsthrougl an opening Til in the casing of the chamber. 37 and into contactwith the top part of a convolution of the coil 28 so that by expansion of the latter the rod 519 will also be moved longitudinally to eilect'movement of the cut-oil valve llto cut down or retract the supply of gas to the burner in the manner already described.

- hen the supply of gas is thus restricted the burner flame consequently will be decreased so that the heat generated will be likewise decreased and the amount of heat supplied to the coil 28 and the receptacle l0 aind the water contained therein will be. decreased so as to prevent an explosion of any of the parts including the chamber l0 and the coil contained in the gas heated chamber.

In order to prevent a. movement oi'tl cut-oil valve H a sutlicient distance to completely close the burner opening l5. I have provided means for limiting the longitudinal movement in one direction of the rod 49. The. means provided for this purpose consists of a bracket 56' secured upon the side of the range structure, as shown in Fig. 3 of the drawings. which bracket is'provided with an opening through which the rod 4-9 would be dangerous to permit movement oi the cut-oil valve M a distance sutlicientli' great to completely close the opening: -35 and thereby cut of? entirelv the Suppl; of gas. If this should happen gas would be permitted to escape from the burner and through the chamber '27 into the kitchen chamber as soon as the coil and the water in the receptacle 40 became somewhat cooled.

Although I have shown in Fig. 5 a burner of novel sha e and construction which I have found to be Yer ellicient. it will be understood that in so far as my invention is broadly concerned a burner of any other suitable construction ma v be employed.

I claim r l.
